As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd., we are proud to present our PLC Controlled Rising Film Evaporator made of premium 304 Stainless Steel, with a heat transfer area ranging from 0.5 to 2 m². This compact yet powerful evaporator is designed to meet the demanding needs of chemical, pharmaceutical, and food processing industries, offering precise process control, high thermal efficiency, and reliable operation. Our factory, spanning 10,000–30,000 square meters, has been dedicated to manufacturing advanced evaporation equipment since 2015, exporting to over 20 countries worldwide.
The rising film evaporator operates on the principle of thin film evaporation, where liquid flows upward through heated tubes as a thin film, maximizing heat transfer and minimizing residence time. This design is particularly effective for heat-sensitive products, ensuring gentle evaporation without degradation. Our PLC control system allows for real-time monitoring and adjustment of temperature, pressure, flow rate, and vacuum level, providing consistent product quality and operational safety.
Key Features & Technical Specifications
- High-Quality Material: Constructed from 304 stainless steel (SUS304) for superior corrosion resistance, durability, and easy cleaning. Suitable for a wide range of media including acidic, alkaline, and organic solutions.
- PLC Control: Equipped with a programmable logic controller (PLC) and touch screen HMI, enabling fully automatic operation, data logging, remote monitoring, and alarm functions. Parameters can be customized to match specific processes.
- Efficient Heat Transfer: Heat transfer area of 0.5–2 m² (customizable within this range). The rising film design provides a high heat transfer coefficient, reducing energy consumption and improving evaporation efficiency.
- Compact Footprint: Space-saving vertical design, ideal for laboratories, pilot plants, and small to medium production lines. The unit can be mounted on a skid or frame for easy integration.
- Flexible Operation: Can operate under atmospheric or vacuum conditions (vacuum pump optional). Vacuum operation lowers boiling points, allowing gentle evaporation of heat-sensitive materials.
- Easy Maintenance: Quick-disconnect fittings, sight glasses, and clean-in-place (CIP) capability simplify maintenance and cleaning, reducing downtime.
- Safety Features: Over-temperature protection, emergency stop, pressure relief valve, and level sensors ensure safe operation.

Advantages for Your Business
- Precision Control: The PLC system ensures repeatable process conditions, reducing batch-to-batch variation and improving product consistency.
- Energy Savings: The rising film design achieves high heat transfer coefficients, allowing lower temperature differences and reducing steam or thermal oil consumption.
- High Yield: Gentle evaporation minimizes product degradation, especially for heat-sensitive compounds like vitamins, flavors, and pharmaceutical intermediates.
- Low Maintenance: 304 stainless steel construction resists corrosion and scaling. The CIP system (optional) allows quick cleaning without disassembly.
- Scalability: The 0.5–2 m² range is ideal for R&D, pilot testing, and small-scale production. We can also provide larger units based on the same design.
- Global Compliance: Our manufacturing processes are certified under ISO9001, ISO14000, HACCP, and other standards (certificates available upon request). The equipment meets international safety and quality requirements.
Typical applications include concentration of fruit juices, milk, whey, herbal extracts, chemical solutions, waste water treatment, and solvent recovery. The PLC-controlled rising film evaporator is also widely used in the production of glycerin, sorbitol, urea, and other high-value chemicals.

Frequently Asked Questions
-
Q: What is the difference between a rising film evaporator and a falling film evaporator?
A: In a rising film evaporator, the liquid enters from the bottom and flows upward through heated tubes, forming a thin film. This design is suitable for low to medium viscosity fluids and provides higher heat transfer coefficients at lower temperature differences. Falling film evaporators have liquid flowing downward by gravity. Both have their advantages; we can recommend the best type for your application. -
Q: Can this evaporator handle heat-sensitive materials?
A: Yes, the rising film design with short residence time and the option of vacuum operation makes it ideal for heat-sensitive products such as enzymes, vitamins, and pharmaceutical intermediates. The PLC control ensures precise temperature management. -
Q: What is the maximum concentration ratio achievable?
A: The concentration ratio depends on the feed properties, desired final concentration, and operating conditions. Typically, ratios of 2:1 to 10:1 are achievable. We recommend lab testing or pilot trials for specific requirements. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer remote guidance via video call, and for larger orders, we can arrange on-site technical support. Detailed manuals and drawings are provided with each unit. -
Q: What are the power requirements for the PLC system?
A: The PLC control panel requires a standard 220V or 380V power supply depending on your region. The evaporator itself does not consume significant power; the main power consumption comes from the feed pump, vacuum pump, and control system (total -
Q: Can the material be upgraded to 316L stainless steel?
A: Yes, 316L stainless steel is available upon request for applications requiring higher corrosion resistance, such as chloride-containing solutions or pharmaceutical use. Please specify your requirements. -
Q: What is the delivery time for this evaporator?
A: For standard configurations (0.5–2 m²), delivery time is typically 30–45 days after order confirmation. Customized units may take 45–60 days. We can expedite urgent orders. -
Q: Do you offer spare parts and after-sales service?
A: Absolutely. We maintain a stock of common spare parts (seals, sight glasses, gaskets, etc.) and provide quick shipping. Our after-sales team is available 24/7 for technical inquiries.
